Introduction

In mathematics, ratios are used to compare the size of two or more quantities. When we are given a ratio, we can use it to divide a quantity into parts in proportion to the ratio. In this article, we will explore how to share £8 in the ratio 3:5.

Understanding Ratios

A ratio is a way of comparing two or more quantities. It is usually written as a fraction, with the first quantity as the numerator and the second quantity as the denominator. For example, the ratio 3:5 can be written as 3/5. When we are given a ratio, we can use it to divide a quantity into parts in proportion to the ratio.

Sharing £8 in the Ratio 3:5

Understanding Ratios

Sharing £8 in the Ratio 3:5

To share £8 in the ratio 3:5, we need to find the total number of parts in the ratio. In this case, the total number of parts is 3 + 5 = 8. This means that the ratio 3:5 is equivalent to 3/8 and 5/8.

Calculating the Amount for Each Part

To calculate the amount for each part, we need to divide the total amount (£8) by the total number of parts (8). This gives us £1 per part.

Calculating the Amount for Each Person

Now that we know the amount for each part, we can calculate the amount for each person. The first person gets 3 parts, so they get 3 x £1 = £3. The second person gets 5 parts, so they get 5 x £1 = £5.

Q&A

Q: What is the ratio 3:5? A: The ratio 3:5 is a way of comparing two quantities, where the first quantity is 3 and the second quantity is 5.

Q: How do we share £8 in the ratio 3:5? A: To share £8 in the ratio 3:5, we need to find the total number of parts in the ratio (3 + 5 = 8) and then divide the total amount by the total number of parts (£8 ÷ 8 = £1 per part).

Q: How much does each person get? A: The first person gets 3 parts, so they get 3 x £1 = £3. The second person gets 5 parts, so they get 5 x £1 = £5.

Q: What if we want to share £8 in a different ratio? A: If we want to share £8 in a different ratio, we need to find the total number of parts in the new ratio and then divide the total amount by the total number of parts.

Q: Can we use ratios to divide quantities in real-life situations? A: Yes, we can use ratios to divide quantities in real-life situations. For example, if we have 12 cookies and we want to divide them in the ratio 2:3, we can use the ratio to find the amount for each person.

Conclusion

In this article, we explored how to share £8 in the ratio 3:5. We learned how to find the total number of parts in the ratio, calculate the amount for each part, and calculate the amount for each person. We also answered some common questions about ratios and how to use them in real-life situations.
